Nv4_disp.dll

hi all,

maybe my problem now is more a hardware issue than a v4-bug. with my new geforce 8800gt i always get a blue screen with an error message (referring to the nv4_disp.dll), when i implement shaders where more than one vertex texture is loaded via the tex2Dlod-semantic. sounds weird, i know…
i found out, that this could have many reasons and already tried so many things by now (mobo-bios-update, reinstallung xp SP2 and DX9, changing video card drivers,…i don’t expect any solutions to fix that, but did anybody else experience such a problem when working with shaders?

thx in advance,

flux
